BOTTLE CLOSUBE.

'Application led December 11, 1925. Serial No. 74,788.

, Thisinventio'n relates to improvements in bottle closures, closing and sealing the mouths of the.com`

mon milk bottles, and has for its objectgto 5 provide a cap or closure, preferably made products; vthe said markings preferably being applied at a number of points and adjacent the perimeter of the cap. And a 2o further object is to apply an adhesive to the underside of the flexible apron at a number of points adjacent the margin of the apron, preferably at or'near the stenciled or printed characters, for positively sealing and preventing the rufliing or distortion of the apron by handlinlg, and for excluding dirt and germs, as we '.as obviating the danger of unauthorized persons removing or otherwise tampering with the original closure, or

,extracting or substituting the contents of the bottle without detection; the said adhesive preferably being odorless and tasteless, and of such nature lthat a satisfactory seal may be e'ected by utilizing the moisture 85 that usually collects upon thesurface of the flaring mouth during the fillin .of .the b Ottle; the said adhesive being 'so isposed that the sealing of the closure ma be effected by the parts of the filling mac 'ne that apply the caps object of the present invention to inc udo the application of heat to the flexible flange of the closure, case the latter requires higher than normal temperature for effecting the ready and positive sealing of the cap.

This invention relates particularly to improvements of the closures shown and described in the pending jointv application, filed August 31 1925, erial No. 53,689. The various features and parts of the inventionv will be` understood from the detailed description which follows, and by refdesigned particularly forv annular ledge that usually to the filled bottles.` It bein an p for softening, the adhesive, 1n

'In the drawin 2 represents the neck of an ordinary mi bottle. 3 is-the flaring mouth, and 4 represents the` annular'shoulder or ledge, that forms the bottom of the recess, in which lthe closure is usually disflange. section,

In the present case, the closure 4for the bottle, follows generally the onstruction and arrangement plication, and comprises a disc-shaped central body 5, having a diameter substantially equal to the diameter of the recess and the ledge 4, the said body being formed with an integral relatively broad flexible apron or fiange 6, w 'ch 1s folded inwardly, at its junction with the disc 5,.for provlding an annular socket or groove 6 the said apron ythen being folded outwardly for providing a relatively broad annular convex portion 6",

The disc 5 is preferably-dished or depressed, as at 5, for stiff'ening the same,'and for resistin upward or outward flexing, by the weight o the contents of the bottle, or by the expansion of air, which is usually confined in the void as 2', by the Yquick and forcible insertion 0 face view of the cap; showing is applied; also showl shown in the pending aP' be read1ly the closure, as shown in Fig. 1. The depression 5a is surrounded by a plane annular margin 5", that seats firmly upon the ledge 4. In order to effect the ready folding'and rolling of the main cap, as shown and described, the gage of the paper is preferably about the same as ordinary ledger bond, (shown thicker in drawing for clearness), and owing to the extreme lightness of the material, the disc 5 requires suitable reinforcing for preventing the disc from being unduly flexed or distorted during the capping operation. To this end, a circulai` member 7l is provided, which may be made from pulp or tag board of relatively heavy gage for stiffening the portion of the cap that actually effects the liquid seal of the bottle mouth. The central portion .of the member 7 is preferably correspondingly dished, as at 7 and intimately engages the disc 5. The member 7 is formed with a plane margin 7a, which is partially received iii and is gripped by the infold of the flanfre 6, whereby said member is firmly held in place before, as well as after the cap is applied to the bottle mouth.

In practice it has been found that owing to the extreme thinness of the web of the convex fiange 6a, the free margin of the latter tends to spring away from the flared surface of the mouth, when the bottle is roughly handled, thereby admitting dust or germs to the surface over which the contents of the bottle are oured. To overcome this unsanitary con ition, and also to provide against unauthorized removal of the cap, or tampering with the contents of the bottle, I provide simple and effective means for sealing the said flange, which consists of applying to, or coating the concave underside of the apron 6E, with a suitable adhesive, such as parafin, um arabic compounds, or other odorless and tasteless material, the said adhesive preferably being applied at two or more points and adjacent the periphery of the cap, as shown at 8, in Figs. 2, 3 and 4. This point-sealing has proven very effective for holding the relatively light gage apron in close contact with the flared mouth, and When an adhesive of the proper character is employed, it is impossible for the apron to be loosened, without tearing or otherwise defacing and showing that the cap has been tampered with. The shaded portions 8 and 8 in Figs. 3, 4 and 6, show different ways/- of applying the adhesive. This adhesion of the apron to the bottle may be effected by various means according to the peculiar nature of the adhesive, as b wetting the mouth of the bottle, or by app ying heat immediately after the cap has been forced into the mouth. When the adhesive consists of gum arabic, and certain other ingredients it has been found that the moisture that usually collects upon the surface of the bottle mouth an extremely simple yet effective manner, by

stenciling or printing letters, as N, which may stand for Netherland, or S for Syracuse or Smith, at or near the free margin of the apron 6a, as Shown in Figs. 2, 3, 4 and 5. The stenciling or printing of the letters, and the spots of the adhesive, may coincide, as shown in Figs. 2 and 3, or the initials may be staggered relatively to the adhesive, as shown in Fig. 4. JV hen the adhesive is in the form of a relatively heavy wax, it is preferably applied at the stencil points, where the margin of the apron is weakened by cutting out the letters, and in case heat is required to soften the wax, the letter openings facilitate the quick melting of the wax, as Well as the capillary spreading of the same beneath the apron. Either the initials or the adhesive may be used alone, if desired, as shownin Figs. 5 and 6. Where a thin layer of the adhesive is employed, it may be applied to the underside of the caps when they are made, like envelopes are treated. When the heavier waxes are employed, they may be applied in the form of wafers, or the wax in proper viscous state may be applied by the machine that performs the capping operation.

By the use of the adhesive, as herein shown and described, a much thinner sheet or web of paper stock may be employed for the larger member of the closure, which is very desirable, inasmuch as it enables the apron oa to be more readily flexed against the ared portion of the mouth, and the provision of the letters or other characters denoting initials of the dealers, not only serve to identify the products contained in the bottles, but when the said characters are stenciled, as shown in Fig. .2, and the adhesive is applied' so as to coincide with the stencils, any attempt to remove the closure by breaking the several seals, results in tearing and multilating the apron and showing tampering.

Having thus described my invention, what I claim, is-

l. A bottle closure comprising a disk having an annular apron adapted to overlie the upper edge of a bottle, said apron having perforations forming marks of identification adjacent the marginal edge along the circumference thereof and adhesive ap lied to the under side of the apron where y a tight seal between the upper edge of the bottle and apron is obtained.

2. A bottle closure comprising a disk hav- 1nD upper edge of a bottle, said apron having marks of identification providing weakened portions adjacent the marginal edge and spaced from each other and adhesive applied to the under face of the apron andfextending into said weakened portions whereby mutilation of the cap is obtained when an attempt is made to remove the same.

3. A bottle closure comprising a disk having an annular apron adapted to overlie the upper edge of a bottle, said apron having o' an annular apron `adapted to overlie the' perforations forming marks of identification at spaced intervals throughout the circumference thereof, and adheslve applied to the under face of the a ron and extending upwardly into the per orations to provide an added anchorage for the adhesive and to further seal the perforations whereby to prevent the passage of dust therethrough and the accumulation of the same upon the upper edge of the bottle.

In testimony whereof I aix my signature.
